Leeds United are in talks to sign midfielder Stuart Dallas from Brentford, according to Sky sources.
Motherwell have signed Middlesbrough goalkeeper Connor Ripley on loan.
The 21-year-old, who enjoyed a brief spell on loan with Wanderers during the latter stages of the season, will sign a one-year deal.
Robinson, who primarily operates as a central midfielder, progressed through Southampton's youth academy and made his senior debut in September 2012.
"I'm really excited to get going," he said in an exclusive interview with bwfc.co.uk.
"Obviously it's going to be different after being at Southampton for so long, but I can't wait for a different challenge".
